Error description

  • Brief Description of issue:
    Garbage attributes without data elements be created after rename
    roles.
    
    Expected Results
    Attributes created with data elements successfully.
    
    Actual Results
    Attributes created without underlying data elements.
    
    Impact
    This breaks client's data model.
    
    STEPS to REPRODUCE
    Create a New Entity Relation Diagram
    Drop 2 entities
    Edit Entity_1
    Create 2 PK named Ent 1 PK 1 and Ent 1 PK 2
    Draw TWO Identifying Relations IR1 and IR2 from Entity_1 to
    Entity_2
    Edit IR1
    Under Foreign Keys, add roles named Ent1 Role 1 and Ent1 Role 2
    OK
    Save diagram
    Run Update FK
    Everything should be good
    Edit IR1
    Rename the roles
    OK
    Save diagram
    Update FK

    Issue is caused by a defect in the code whereby FK
    attributes which must be deleted during FK propagation are
    not being properly removed from Access Paths and upon saving
    of Access Paths erroneous attributes with no Data Element
    values and unconnected to their owning entities will be
    created. For all intended purposes, these Attributes are
    considered orphans.
    

Problem conclusion

  • The issue has been addressed so discarded FK attributes are
    properly removed from Access Paths.
    
    Workarounds to delete the orphaned attributes and also
    orphaned columns if they are created is to run the following
    VBA macros:
    
    Here are two macros. One which deletes orphan Attributes and
    one which deletes orphan Columns. It is possible that the
    same defect, in a similar scenario using Physical Data Model
    diagrams could have created orphan Columns.
